Specicaton of Letters Patent No. 17,382, dated May 19, 1857.

To all wh-0m t may concern Be it known that I, JAMES LAsHRooKs, ofOwensboro, in the countv of Daviess and State of Kentucky, have inventedcertain new and useful Improvements in Hand- Planes; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

The nature of my invention consists in the use of a curved bit whereby Iam enabled to use a handle on all planes however short without anyinconvenience.

In order that those skilled in the art may use and manufacture myinvention I will proceed to describe operation and construction.

In the accompanying drawings which make a part of this specificationFigure l is a side elevation. Fig. Q is a plan view of the bit. Fig. 3is a side elevation of the bit.

In Fig. l A .is the stock, B the handle, C the bit, I) a plate of steelextending into the stock and attached to the handle. L is a screwpassing through the bit C for the purpose of holding in its position, Ethe head of said screw. (l seen in dotted line shows a screw forattaching bit F to bit C. f/ is a slot in the stock in which screw Gworks.

In Fig. Q C is t-he bit, L the screw, a a slot through which screw Grpasses attach ing the two bits.

In Fig. 3 C the main bit, F the cap bit,

G screw for attaching them, L screw for stationing the bits at anydesired point.

In the operation of my invention the bit and cap are first fastenedtogether by means ot' the screw G and adjusted to the position requiredin the stock and then set to the depth required for planing by means ofscrew L which presses against plate D, I). The plane is then ready foruse. It will be seen that as the bit C is pressed by means of screw Lagainst plate I) the effect of the leverage is to press the lower end ofthe bit firmly against the lower side of the plane stock through whichit passes thus making` a more solid and firm plane than by any otherdevice known, doing away entirely with wedges in my curved bit plane.

One of the peculiar advantages of my invention consists in causing thebitto curve forward and thus allowing ine room to set a handle on allshort or smoothing planes, which cannot be done by any other shaped bitheretofore known and which object is of great importancein short planes.It is also applicable to all planes.

Having thus described my invention what I claim is- The curved planeiron C and cap F in combination with the curved back rest and slottedplate D operating as described and for the purpose set forth.
